SIDE ARCH BRICK.

Application filed March 22, 1923. Serial No. 628,902.

To all whom it may concern:

Be it known that EDWARD M. QARROLL, a citizen of the United States of America, residing at Sanford, in the county of Orange and State of Florida, has invented certain new and useful Improvements in Side Arch Bricks, of which the following is a specification.

My invention relates to new and useful improvements in side bricks for locomotive arches and has for an object to provide a brick which will be supported at its one side by a lug, which is spot-welded to the side sheet and is supported at its opposite side by the arch pipe.

Another object of the invention is to provide a side brick wherein its two points of support are in the same horizontal plane so that there will be no wedging action between the side sheet and the arch pipe. A wedging.

action is a disadvantage, as it often causes the arch pipes to leak where they join the fluesheet thus making it necessary to renew the arch pipes even more often than would otherwise be necessary.

Still another object of the invention is to provide a side brick which will allow for the variation from parallelism between the side sheet and the arch pipes. Still another object of the invention is to provide an arch brick wherein the fiat side of the brick will always be straight against the side sheet while its opposite face will be supported on the arch pipe even though the pipe is not parallel with the sheet, thus making it impossible for the side brick to fall out of place or to push the pipe out of its proper position. I 1

With these and other objects in view, the invention consists in certain new and novel arrangements and combination of parts as will be hereinafter described and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment of my invention? Fig. 1 is a view partly in section showing a portion of a locomotive fire box with one arch tube therein and the arch bricks thereon.

Fig. 2 is a fragmentary diagrammatic cross-sectional view showing the arch tubes, side bricks and center arch bricks in posi tion.

Fig. 3 is a similar fragmentary view'ona somewhat enlarged scale.

Fig. 4 is a fragmentary top plan view showing two side bricks and two arch bricks in position.

Fig. 5 is a detailed view showing one of a series of lugs welded to the side sheet and the washer therefor.

Fig. 6 is a perspective of the side brick from one, angle.

Fig. 7 is a perspective of the side brick from the opposite side.

Fig. 8 is a perspective of one form of center arch brick which may be used with the side-brick, and

Fig. 9 is a still further perspective of the side brick.

Referring more in detail to the drawings, there is shown in Fig. 1 the conventional fire box having the side sheet 1, and the arch pipe 2, and as known, in most instances, there are four arch pipes in each fire-box.

The present invention contemplates spot welding a plurality of lugs similar to the lug 3 shown in Fig. 5, to the side sheet 1, and in planes paralleling and opposite the side arch tube 2. These lugs 3 are pointed at their inner end as at 4 so that they may p be spot-welded to the side sheet 1 as shown in detail in Fig. 5. Adapted to enclose these lugs are the washers 5 which are rectangular inshape and are rovided with the central openings 6 as may e seen in Figs. 5 and 7.

The purpose of the washer is two-fold in that it prevents the lugs from being affected by the heat and furthermore, presents a eater bearing surface to the side bricks Yvhich will now be described more in detai As may be seen from the several figures,

the side brick presents a curved upper and lower surface and is provided at its one side as may be seen in Fig. 3, while its opposite side is undercut or, in other words, provided with the groove 9.

It is to be noted, also, that the side provided with the groove is curved slightly from its opposite ends towards the center as may be seen in Fig. 4; the object of this being that it will accommodate itself to the tube 2 even though the same be'slightly bent or distorted from its original parallel position with the side sheet. Formed within the lug 8 and centrally thereof, is the rectangular depression 10 whlch is just large enough to accommodate the washer 5, heretofore mentioned.

lin the several figures, I have shown the center arch brick 11 which may be used with my side-brick, this arch brick being patented -by me on August 13, 1918, PatentNo.

1,275,386, although it is to be understood that any other form of center arch brick anight be used with my side-brick.

The installation of the side brick simply calls for the spot welding of the lugs and the provision of the washers, after which the side brick may be laid in place. Both sides of the brick are supported in the same horizontal plane so that there is no tendency for the bricks to wedge the tubes out of their proper position.

Furthermore, the brick may be used either as right hand or left hand ones by simply turning'them around so that. one form of mold is necessary, and thus new bricks may be quickly and readily inserted on either side of the fire box.

From the foregoing it will be understood that I have provided a sidebrick which is relatively simple in construction; quickly and readily applied; will not jam the arch tubes, and will, on the other hand accommodate itself to any position the arch tube may have taken. v

Many slight changes might be made without in any way departing from the spirit and scope of the invention.

Having thus described my invention, what If claim as new and desire to secure by Letters Patent is 1. 'A side brick for locomotive arches, curved throughout its upper surface and curved substantially throughout its lower surface, the brick provided with a depending flange on one side, which flange is at right angles to the bod of the brick, the outer surface of this form a relatively wide contacting area, and this flange provided with a depression to ange being flat to neearae 2. A side brick for locomotive arches, one

side of the brick being provided with a downwardly extending flange, which flange is substantially at right angles to the body of the brick, thereby forming a flat side, the depth of which is greater than the mean thickness of the body of the brick, said flange provided with a depression in its face at a point between the lower and upper.

extremities thereof, and the opposite side of the brick being undercut to form a supporting ledge. 1

3. A side brick for locomotive ,arcnes,

curved throughout its upper surface and provided with a downwardly depending flange on its one side, the depth of the flange being greater than the mean thickness of the body portion of the brick, and the lower surface of the brick arcuate and merging into said flan e, the said flange provided on its outer sur ace with a depression for the reception of the supporting means, and the -said flange being arranged perpendicularly with the body of the brick, the opposite side of the brick having an under cut portion extending throughout its length to form a supporting ledge. 4

4. In combination with a locomotive side sheet having'lugs welded thereon, washers fitting over said lugs, a plurality of arch tubes, arcuate side bricks, said bricks having a' perpendicularly arranged flange at their one side, the depth of which is greater than the mean thickness of the brick, said flange provided with a depression formed therein to receive said washers, the opposite side of each brick being provided with an undercut portion to rest on. saidtube.

In testimony whereof ll aflix my signature.
